To figure out how much work is done in real life, you can use a simple formula:

Work = Force × Distance × cos(θ)

Here’s what these words mean:

• Force is how hard you’re pushing or pulling. It’s measured in Newtons (N).
• Distance is how far something moves. It’s measured in meters (m).
• θ (theta) is the angle between the direction of the force and the direction of movement.

Let’s say you’re pushing a box across the floor.

If you push with a force of 10 N and move the box 5 m, you can find the work done like this:

Work = 10 N × 5 m = 50 Joules

Remember, when the angle (θ) is 0°, it means you’re pushing in the same direction as the movement.

In that case, it’s easier to calculate because cos(0) = 1.

Isn’t it amazing how we can measure energy in our everyday activities?
